A light microscope that makes the specimen appear light on a dark background is called a darkfield microscope. Darkfield microscopy illuminates the specimen with oblique light, making it stand out against the dark background, which enhances contrast and visibility of transparent or low-contrast samples.
To create contrast when using a compound light microscope, you can adjust the microscope's condenser to control the amount of light reaching the specimen. Additionally, you can use stains or dyes on the specimen to enhance contrast by highlighting specific features.
Closing the iris diaphragm reduces the amount of light entering the lens, resulting in a darker image with decreased brightness. However, this reduction in light can potentially improve contrast by reducing any glare or overexposure in the image.
Photographers choose to work with low light in selenium toning because selenium toning has the ability to enhance the tonal range of black and white photographs, making subtle details in shadows more visible and increasing overall image contrast. This can help achieve a more dramatic and visually appealing final print.
The two types of microscopes that can view objects that have been sliced and treated to improve contrast are the light microscope and the electron microscope. Light microscopes use visible light to illuminate samples, while electron microscopes use a beam of electrons for imaging. Both types can reveal detailed internal structures of specimens through contrast enhancement techniques.
The dramatic contrast between light and dark is called chiaroscuro. This technique is commonly used in art and photography to create depth and emphasis in the composition.
I think it's Caravaggio.
Caravaggio used the realism technique chiaroscuro to inspire many painters in his generation. For example, he often showed dirt on the bottom of feet and dirty fingernails.
Tenebrism is a technique involving the intense use of chiaroscuro, where strong contrast between light and dark creates dramatic and dynamic effects in a painting. This technique was notably employed by artists like Caravaggio in the 17th century.
Caravaggio didn't paint by the rules. Instead he painted from real life, taking models from the streets - scandalous at the time. He also used light and dark lighting effects, called chiaroscuro.
Tenebrism is a painting technique characterized by strong contrasts between light and dark areas to create a dramatic effect. It was prominently used by artists like Caravaggio in the 17th century Baroque period.
A dramatic use of light and shade is a term that is often used to describe an image that has a high level of contrast. It can also be used to describe an image that uses light and shadow to evoke an emotion or pinpoint an object (i.e. a spot light that identifies the main figure/object).

Caravaggio creates movement in his paintings through his expert use of light and depth to create a more vivid scene.
This technique is called chiaroscuro, a term that describes the contrast between light and dark in visual arts. It is commonly used in film noir to create a dramatic and moody atmosphere.
